The jrk ships with a 14×1 straight 0.100" male header strip and two 5mm, 2-pin terminal blocks. To provide maximum flexibility, none of these parts are soldered to the board.

For the most compact installation, you can solder wires directly to the jrk pads themselves and skip using the included hardware. The included hardware allows you to make less permanent connections. You can break the 14×1 header strip into an 8×1 piece and two 3×1 pieces and solder these strips into the jrk’s I/O pads.
